On the other hand, electrical switchboards are designed for use with lower voltages, typically below 600 V. For instance, a typical residential switchboard has a voltage rating of 120/240 V. Commercial and industrial facilities, on the other hand, may have switchboards with ratings of up to 600 V. Switchgear is designed to contain an electrical arc and comes with more elaborate insulation methods such as air, gas, oil, solid dielectric, and even vacuum. Because conversion is continuous, there is no requirement for detection of input power disturbances in order to protect the load. I dont think there is a definition for a distribution panel. When the primary is energized with alternating current, the primary coil generates a magnetic field that varies in magnitude and direction with the input power. A UPS maintains power to its load during blackouts, brownouts, voltage sags and swells, loss of a single phase and other system disturbances, protecting from both loss of power and from damage. Switchgear. This table is based on gear ratings and sizes by ABB, Eaton, and Schneider Electric for equipment commonly used in residential and commercial facilities. There are major differences in the hardware and design of the two systems. Kind of old and I apologize for resurrecting a "zombie thread", but I don't think the entire question was answered and I happen to know this very well. Switchgears are higher voltage than PDCs, and supply power to the transformers which feed the PDCs. (note this mainly applies to industrial scale power distribution, not to residential). In this video i have shown you about the working and wiring of main lt switchgear panel in which we are using transformer and generator . Look up the definition for a switched board in article 100.
